Re: Very small X for embedded systems

Hello,

i played around with all the configure-flags listed for the current release of X.org R7.0.
I have no more ideas by now, how to get the Xlib much smaller. I think there is much stuff
in Xlib we do not really need on a small display like our lcd, like fontrendering or anti aliasing.

Greets,
Jonatan Antoni
